Question

当出现问题时，Rails回应了给定的params，它看起来像这样：

参数：

{"utf8"=>"✓",
 "filter"=>{"title"=>"1",
 "address"=>"2",
 "city"=>{"title"=>"3"},
 "people"=>{"name"=>"4",
 "surname"=>"5",
 "patronymic"=>"6",
 "emails"=>{"email"=>"7"}},
 "emails"=>{"email"=>"8"}},
 "sort"=>{"0"=>{"field"=>"",
 "dir"=>"asc"},
 "1"=>{"field"=>"",
 "dir"=>"asc"}},
 "commit"=>"Show"}

但如果看起来像这样，它实际上会更有用：

{
  "utf8" => "✓",
  "filter" => {
    "title" => "1",
    "address" => "2",
    "city" => {
      "title" => "3"
    },
    "people" => {
      "name" => "4",
      "surname" => "5",
      "patronymic" => "6",
      "emails" => {
        "email" => "7"
      }
    },
    "emails" => {
      "email" => "8"
    }
  },
  "sort" => {
    "0" => {
      "field" => "",
      "dir" => "asc"
    },
    "1" => {
      "field" => "",
      "dir" => "asc"
    }
  },
  "commit" => "Show"
}

如何实现？

使用vanilla Ruby，最好的方法是将哈希值转换为JSON：

JSON::pretty_generate(hash_here, :allow_nan => true, :max_nesting => false)

这会输出对象的美化JSON版本（数组，哈希或其他）。它不会是纯粹的红宝石，但它来自基础库，所以不需要安装任何东西。

Rails：更方便的哈希转储
